diaphragm pressure
Industrial valves; Control valves
The proper definition for bench set is the inherent diaphragm pressure range, which is the high and low values of pressure applied to the diaphragm to produce rated valve plug ...
dynamic unbalance
Industrial valves; Control valves
The total force produced on the valve plug in any stated open position by the fluid pressure acting upon it. The particular style of valve, i.e. Single-ported, double-ported, ...
feedback signal
Industrial valves; Control valves
The return signal that results from a measurement of the directly controlled variable. An example would be where a control valve is equipped with a positioner. The return signal ...
gain
Industrial valves; Control valves
The relationship of input to output. If the full range of the input is equal to the full range of the output, then the gain is 1. Gain is another way to describe the sensitivity ...
control valve gain
Industrial valves; Control valves
The relationship between valve travel and the flow rate through the valve. It is described by means of a curve on a graph expressed as an installed or inherent characteristic.
flow characteristic
Industrial valves; Control valves
The relationship between valve capacity and valve travel. It is usually expressed graphically in the form of a curve. Control valves have two types of characteristics inherent and ...
rangeability
Industrial valves; Control valves
The range over which a control valve can control. It is the ratio of the maximum to minimum controllable flow coefficients. This is also called turndown although technically it is ...
